1. sin(x+20) = cos(2x+10) 2. sin (2x+14) = cos(x-5)

lakkis [162]

Answer:

x=20°

x=27°

Step-by-step explanation:

sin(x+20)=cos (2x+10)

=sin (90-(2x+10))

so x+20=90-(2x+10)

x+20+2x+10=90

3x=90-30

3x=60

x=60/3=20

2x+14+x-5=90

3x+9=90

3x=90-9=81

x=81/3=27

Are 3:5and 1:2 equivalent

german

Answer:

No. They are not equivalent.

Step-by-step explanation:

$\frac{3}{5} \neq \frac{1}{2}$

=> $\frac{6}{10} \neq \frac{5}{10}$

Therefore, 3/5 and 1/2 are not equivalent.

Hoped this helped.

Find the value of the variable and MN if N is between M and Q. Round to the nearest hundredth if necessary.

Rudiy27

Answer:
MN = 4 units

Explanation:
1- getting the value of m:
We are given that:
NQ = 4m and NQ = 12
This means that:
12 = 4m
$\frac{4m}{4} = \frac{12}{4}$
m = 3

2- getting MQ:
We are given that:
MQ = 5m + 1
We have calculated that:
m = 3
Therefore:
MQ = 5(3) + 1 = 15 + 1 = 16 units

3- getting MN:
We are given that point N is located somewhere between points M and Q.
This means that:
line MQ can be divided into two portions: MN and NQ
This also means that:
length of MQ = length of MN + length of NQ

We have calculated that:
MQ = 16 units
We are given that:
NQ = 12 units
Therefore:
16 = length of MN + 12
length of MN = 16 - 12
length of MN = 4 units

Hope this helps :)
